Agree the 42 & 52 are cheap 'n' nasty, same hw as 40/50 inside. No traffic and very, very basic. I have both 40 and 50 which will convert safely and easily to x2: [Only registered and activated users can see links. ]. Doesn't add anything, just changes to the 2013 range icons is all.

Navigon? [get thee behind me Satan!] . Go away ... i know nothing about them. Someone else may be able to help you although the later ones might be more 'garmin-like' since they bought them out.

PM you on the other.
